(Devarim 16:9) "And you shall cook it and eat it, in the place, etc.": We are hereby taught that if pieces of it fell (from the oven), it is returned (to the oven) whole, and not piece by piece. These are the words of R. Yehudah. R. Yossi says: On the Sabbath, in any event it is forbidden. On yom tov, in any event it is permitted.

"and you shall betake yourselves in the morning and go to your tents": We are hereby taught that they must sleep over (in Jerusalem).

This tells me only of themselves (as being required to remain overnight in Jerusalem). Whence to I derive (the same for) fowl, meal-offerings, wine, frankincense, and wood? From "and you shall betake yourselves in the morning" — All of your "betakings" shall be from the morning on.

R. Yehudah says: I might think that "the small Pesach" (Pesach Sheini, viz. Bamidbar 9:10-12) also requires remaining overnight. It is, therefore, written "and you shall betake yourselves in the morning and go to your tents. (8) Six days shall you eat matzoth." What requires six days requires remaining overnight — to exclude the small Pesach, which requires only one day. The sages say: It (Pesach Sheini) is not worse than wood and frankincense. (i.e., Just as they require remaining overnight, so, Pesach Sheini.)

R. Shimon b. Elazar says: One verse states "Six days shall you eat matzoth," and another, (Shemoth 13:6) "Seven days shall you eat matzoth!" — Six of the new grain (after the omer offering on the second day); seven of the old grain.
